The graph of y = x2 = 4x is shown below.

(a) What are the coordinates of the point Q? Do they satisfy the equation?
(b) What are the coordinates of R? Do they satisfy the equation?
(c) If the coordinates of the point P on the graph are (a, b), how are a and b related?
(d) What are the x-values of the points on the graph whose y-coordinates are 0? Are these x-values solutions to the equation x2 - 4x = 0?
